Fathom It!</a> is a shareware program for playing and solving these puzzles.  
This gives you
a program to let you solve puzzles on screen, as well as a rule based solver. 
The trial version contains 80 puzzles: 10 each in four levels of difficulty
and two sizes (7x7 and 10x10.)  The full version contains thousands. 
All puzzles distributed can be solved by the rule based solver without 
backtracking.  However puzzles exist which it cannot solve, but they are not
distributed.
